IMPROVEMENT nv HORSE-POWERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that we, GonNnLlUs AULTMAN and J 0- sErH ALLONAs, both of Mansfield, in the county oi" Richland, and State of Ohio, have invented certain new and useful Improvements in the Construction of Horse-Powers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, and the letters of reference marked thereon, making part of this specification, in which- Figure l is a plan or top'view;

Figure 2 is a vertical sectional view through the line x f1 n g 1 `igure 3 is a longitudinal sectional view of the' connecting-rod and universal joint, taken t right angles to the'view of same devices, as given in tig. 2;

Figure 4 is a vertical sectional .view ot' the upper frition-wheels, and the devices for mounting the same an Figure 5 represents a frame-bolster.

Similar letters ot' reference denote similar parts in all the gures. l

The invention relates to that class of horse-powers in which the power is applied to the master o'r main driving-wheel, by means of horses traversing a circular track, and attached to arms rigidly connected with said master-wheel, the speed of which is multiplied to any desired extent, by means' of a system of wheels and pinions, and then transmitted to the threshei, or other machinery', as required.

The invention will be fully understood from the following description.

In the drawing- A A is the frame, represented as being vmounted upon wheels.

B B B B are levers secured to the master-wheel O by means of the sockets b b b b, this master-wheel being cogged upon its inner diameter. v v

Supported upon, and .firmly secured to the frame A A, is a circular metallic.bed piece, D, and project` ingvertically from this bed-piece is a series of studs or spindles, d d d, serving as axles for the spur-wheels `E and pinionsE, engaging with the master-wheel C.

An intermediate series of spurs or standards d, rising from the bed-piece D, is connected with each other, also with the series marked d, by a rim or disk, D', secured rigidly in placev by nuts d2 upon the ends of spindles d and standards d1. l The standards d are shorter than the spindles d, consequently the rim-Dassuines an undulating or serpentine form in its course from one to anotherof these' studs; therefore they (the studs d) are supported and braced much more eiiciently than they would be if both studs and standards were all of the same height,

and the rim Doccuped, throughout its entire extent, a plane parallel tothat occupied by the bed-piece D.

The master-wheel C is provided with a flange, as

shown at c, ig.2, resting upon three or more friction# wheels F, mounted in bearin gs formed upon or attached to the bed-piece D; and the clamps lil', secured to rim- D by nuts d2, prevent vertical displacement of the Aby bevel-wheel G.

, K is an adjustable friction-roller, support-ed upon one of the standards (l1, directly above pinion H', and serves to keep the bevel-wheel G in proper relation to vthe pinion H', thus relieving the spokes or arms of said bevel-wheel from the strain which would otherwise be thrown upon them, by the tendency of the wheel to rise when passing pinion H'. But there 'is also a tendency in the wheel, at all points in front of this pinion, to rise, the reason for which has been heretofore given, and to counteract this tendency, another friction-wheel, K1, is mounted upon another standard, d1, ata point as nearly ninety degrees in. advance of pinion H as is practicable.

The manner in which these friction-wheels are mounted is clearly shown in g. 4,.iu which d* represents the standard; K, the wheel, supported on a pivot projecting from a wedge-shaped plate, k. rlhe corresponding face kl of the standard 'd1 is also wedging, but in an opposite direction. k2 is a bolt, serving to keep the two parts k k1 firmly together.

The head of said bolt is confined ina T-shaped groove in standardd, andthe relation of parts is such, that an accurate adjustment may be made, and when once made, the wheel K cannot be forced up, exceptby loosening the bolt k2. v

On the outer end of shaft His a hub, h, expanded inthe form of ears, h1 h1, iig. 3.

L is a sleeve or thimble, provided with arib, l, made considerably thicker than the rest of the sleeve, to af ford'a support for the pins It h2, g. 3.- One end of each of these pins is confined in ears h1 h1, byanyv suitable device, and the other ends of said pins are confined to opposite sides ofthe rib l.

The hub Nis also expanded into two ears u n, fig. 2,

and is connected with rib l by a rod or pivot, r11/,pass-y ing nearly through said rib, at right angles to the pins h2 h2, and in the same verticallplane, as shown in iig, 3, thus making a universal joint, the `halves of whic' have the axes, about which they vibrate, intersecting cach other at right angles. y

The rod nl has a button-head fitting intoa countersunk hole in rib l, alld the other end of said rod is secured by a latch-string of leather, or an equivalent device, in such manner that it (the rod) does not project beyond the outer surface of the rib l.

The thimble L serves the double purpose of connecting the two pa1ts hand N of the `coupling, and also of protecting anysubstances from becoming entangled with the rapidly-revolving coup1ing.

Misa tubular sheath, secured at one end to -the huh h, and enclosing a torsion connecting-rod, M', also rigidly fixed in hub h. The other end of rod M' is connected with a hub, Nand provided with a pointer, n, while the outer end of the sheath is free, and provided with a dial, m, 'and from the fact that the dial m and pointer 'n2 are independent of each otherin their movements, they will indicate the amount of tension or twist which is required to be given to the rod` M', in order to move thel machinery to which hul) N may be attached. i

rlhe torsion-rod is found to greatly relieve both the power and the thresher, or other machinery, from undue strain, in case of sudden variation in the work required of them, as in the case of meeting with obstructions.

'lhe sheath M serves to keep lthe rod from being deflected or sprung, when strained, and enables us to use a much lighter rod than we could otherwise do.

li'or the purpose of securing the power vin its position upon the ground, we use the followiugdevices:

0 O are hounds, hinged to the front axle T, as shown in iig. 1.

01 0 are transverse bars.

On the front side ofbar O is a metallic socket, o, attbi-ding a support for the rear end of the tongue, P.

A hammer-strap, o, secures the whiiletrees.

0 is a metallic plate or bracket, cnnectin g the front endsI of the hounds, and furnishing a further support V 4for the tongue.

Attached to the rear axle T is a similar pair of hounds, R R, also hinged and united by a metallic bracket.

Rl R2 is a bolster, 4secured. to the hounds, and provided with stakes fr fr, lying in a plane parallel with the hounds R R.

By removing the tonguevl, and placing-the outer ends of both pairs of hounds upon the ground, and then driving suitable pins or 'stakes through the holes o2 r1, the frame A A is held in any desired position.

Fig. 5 represents a removable frame-bolster, the posts S S titting into the metallic sockets s s, on frame A' A, and supporting said bolster in avertical position when required, as will be now explained.

When moving the power from place to place, it is desirable to have a wagon-box to carry tools, Svc. In order to construct a box, we place the bolster above described in the sockets s s, then swin'g up the rear pair of hounds into a vertical position, thus bringing the bolster R.l on a line with rail S', in frame-bolster, both of which are high enough above frameA A, so that bottom boards maybe laid across from one to the other, without touching the machineryof the power. 'lhev hounds are maintainedin a vertical position b'y being connected with bolster S, by means of cleats upon the bottom boards, or in such other manner` as may b e deemed advisable. The sides of the box are confined by the stakes r fr and posts S S, extending above cross-rail S.

By this arrangement we are enabled to construct a convenient wagon-box, with but little labor, and the employment ot' no superfluous material.

Having thus described our invention,

XVhat we claim as new, and desire to secure by Letters Patent, is

1. The combination of the wedge-shaped `plate k, the standard d1, provided with a wedge-shaped face k1 and the bolt 7.1", substantially as and set forth.

2. The combination of an elastic or yielding connecting-rod or shaft with the horse-power, for the purpose set forth. p

`3. The combination of the sheath M with the torsion-rod or shaft M',for the purpose set forth.

4. The comhination,with the universal joint of the driving-shaft, of the removable ribbed thimble L, which serves to connect the two pai'ts of the joint with the pivots intersecting' each other, and also to prevent straw and other substances becoming' entangled with said joint, as described.
